SURGICAL INSTRUMENT.

Application filed December 2'6, 1922. Serial lib/609,012.

My invention relates in general to the art of surgery and has reference more particularly to an instrument for curetting, scraping and otherwise treating internal and external cavities and organs.

As heretofore practiced, some forms of curetting devices have usually been adapted for use in connection with a so-called irrigating or flushing method requiring a more or less constant supply ofwater or other liquid usually discharged adjacent the endof the device to wash away scraped or otherwise removed dead tissue from the cavity, or other parts treated. In using my device I am able to do away with this flushing or irrigating method and employ a socalled suction method for removing the dead tissue. plate acts in a dual capacity so to speak, in

that it provides a medium for directing the.

suction where needed and also meets all the requirements of an instrument for practicing this kind of surgery.

For the purpose of illustrating the salient features of my invention reference will now be made to the device shown in the accompanying drawing, and in which Figure 1 is a view in perspective of one form of the device, Figure 2 is a longitudinal section on the line II- II of Figure 3, and Figure 3 is a detail view in front elevation of the head of the device.

Referring now to the drawing in detail I propose to use a suction tube (1) which may be made of glass, metal, or any other suitable material, and of difierent sizes and designs to meet requirements, the same formed at one end to receive a flexible hose or the like (2) with the opposite end terminating in a head (3). In constructing the head (3) I suggest cutting away one side of the tube adjacent the end thereof and bend- The device which I conteming over the remaining side to leave a hood or lip (41-) which overhangs the intake opening in the tube. Furthermore, in. constructing the head I desire to make the intake opening provided as above mentioned cup-shaped and flared so as to present a relatively large intake in order to cover as wide an area as possible.

r The overhanging lip or hood forms two. functions, first, since it extends beyond'the side of the tube the 7 edge (5) thereofmay be used as a scraper, and while the same does not need to be sharp or pointed, it may be so made to meet requirements as needed. The function of the hood or lip meets the requirements of a protector, so to speak, in that it guards the walls of the cavity being treated sothat there is no danger of the same being sucked into the intake opening when the device is used for removing pus from cavities. WVhen the device is used for scraping purposes the dead tissue, as it is removed by outer and inner ends of the sloped edge, 7

whereby a flared intake opening is provided 1nto the tubular shank together with a concavo-oonvex 1i p having a rounded side MARK 0. times.
